Disk instability model predictions for β Pictoris. The lower solid curve corresponds to the Toomre criterion which excludes the formation of planets below it. The upper dashed curve corresponds to the cooling criteria which only allows disk fragmentation below it. The allowed formation space is in between. The 1D average detection limit curve has been overplotted (blue solid line) but with a projected separation. The location of β Pictoris b has been overplotted on the graph with the new error bars from Bonnefoy et al. (2013).
